CHURN.

SPECIFICATION forming part of Letters Patent No. 514,358, dated February6, 1894.

Application filed May 9, 1893. Serial No. 473,516. (No model.)

To all whom it may concern:

Be it known that .I, JOSEPH A.-GRANT, of Dyer Brook, county ofAroostook, State of Maine, have invented an Improvement in Chorus, ofwhich the following description, in connection with theaccompanyingdrawin gs, is a specification, likeletters on the drawingsrepresenting like parts.

This invention has for its object to provide an improved churn, theinvention having especial reference to the adaptability of the churn forquick and thorough work, and also to the removal of certain of the partsto facilitate cleaning.

In the drawings Figure 1 represents, in vertical section, a churnembodying this invention, the section being taken on the line x, m, Fig.2, and Fig. 2 represents a horizontal section taken on the dotted lineas, is, Fig. 1, looking up.

Referring to the drawings, the bucket or receiver A, preferably of wood,is suitably shaped and constructed to sustain the various parts, thesame in practice being mounted upon legs or astand of properform, notshown.

A is the cover for the receiver, the same being shown as secured theretoby end hooks a which may be readily thrown back to permit the cover tobe removed. The cover A, at its under side, is provided with a block athe ends of which are provided, as shown, with eyes a to which areattached the links a having their-lower ends hooked to engage eyes at inthe lower block a said block a being sup ported by the links a as shownin Fig. 1.

The dasher blocks 19 are arranged between the blocks a, a and arejournaled therein, as shown, the upper journals 6. of the said dasherblocks being extended vertically through the cover, as shown, for apurpose to be hereinafter described. The blades b on the several blocksare ofi-set from each other, so that during rotation theblades of oneblock pass between the blades of the blocks at either side.

Upon the top of the cover A are arranged two preferably metallic frameplates 0, c separated by posts 0 the journals 1) of the dasher blockshaving their hearings in these plates. The two outer journals b areprovided between the plates 0, c, with bevel pinions din mesh with anddriven by a larger bevel gear d fast on the journal of the middle dasherblock, the bevel gear (1' being in turn in mesh with and driven by thebevel gear d fast on a shaft (i journaled in suitable uprights d mountedupon the cover, the said shaft 01 being provided with a handle 01 bymeans of which the driving gear d may be rotated and thereby causerotation of the dasher blocks with their blades within the receiver. Itwill be seen that the middle dasher block with its blades will berotated in one direction, while the outside dasher blocks and bladeswill be rotated in an opposite direction, the result being a thoroughagitation or stirring of the fluid within the receiver.

The lower bearing block a may be readily removed by unhooking the linksa for cleaning the bearings, the, and the upper frame plate 0,preferably secured to the posts 0 by means of thumb nuts 0 may, byremoval of such nuts, be as readily removed to permit removal of thegears and cleaning of the other bearings, so that all parts and bearingsare easily accessible to be kept clean and pure.

The links a with the eyes a a, are preferably located in grooves a inthe end of the receiver, as shown best in Fig. 2, to thereby hold thelower block a with the dashers firmly in proper position.

When the cover is removed the lower block a with the dashers is removedwith it leaving the receiver perfectly free. i

The gears are so proportioned, as shown, to give the best possiblerelative motion to the several dasher blocks, and the entireconstruction is simple and inexpensive to manufacture.

I claim- 1. In a churn, the combination with a receiver, a covertherefor, and dashers having hearings in and removable with said cover,of a frame composed of the two separable plates 0, 0, thumb screwsconnecting the same, whereby said plates may be readily taken apart forcleaning, and bevel gears arranged between and having their bearings insaid plates and connected with and to rotate said dashers, substantiallyas described.

2,. In a churn, the combination of the folgear wheels between the sameconnected with lowing instrumentalities, viz;a receiver, a and to rotatethe said dashers and driven by cover, abearing block arranged below saidthe said driving wheel, all to operate, subcover and hooked linksconnecting the same stantially as described.
